Subway entrance flood prevention plate capable of being automatically opened
The invention provides a subway entrance flood prevention plate capable of being automatically opened. The subway entrance flood prevention plate comprises a base, a water baffle is movably inserted into the base, a top plate is fixedly connected to the top of the water baffle, a side plate is fixedly connected to the front face of the water baffle, an air cushion is fixedly installed in the base,an air tank is fixedly connected into an operation box, a plugging cap sleeves the can on the right side of the gas tank in a threaded mode, the movable plate is installed on a switch base through aspring, and the switch base is filled with solid salt. The top plate is located on the ground and plays a role in preventing rainwater from flowing backwards when rainfall is small, when the rainfallsuddenly increases and the water level rises to exceed a set value, rainwater enters the operation box and makes contact with solid salt, the solid salt is dissolved when meeting water, the air tank is opened, the air cushion expands after being filled with air, the water baffle is jacked upwards through the top plate, meanwhile, gaps in the outer sides of the water baffles are sealed, and the effect of automatically preventing rainwater from flowing backwards is achieved.
本发明提供一种自动开启的地铁口防汛板，包括底座，所述底座的内部活动插接有挡水板，所述挡水板的顶部固定连接有顶板，所述挡水板的正面固定连接有侧板，所述底座的内部固定安装有气垫，所述操作箱的内部固定连接有气罐，所述气罐右侧的罐头上螺纹套接有封堵帽，所述活动板通过弹簧安装在开关座上，所述开关座的内部填充有固体盐。顶板位于地面上，在雨量较小时起到防止雨水倒灌的作用，当雨量剧增，水位升高超过设定值后，雨水进入操作箱内与固体盐接触，固体盐遇水溶解，使气罐打开，气垫充满气后膨胀，通过顶板将将挡水板向上顶起，同时将挡水板外侧的空隙封闭住，起到自动防止雨水倒灌的作用。
